Abstract:

The objective of this study was to determine the influence of luminaire type on the susceptibility of HMIPs to vortex shedding using a computational fluid dynamics (CFD) modeling approach. Two types of luminaires were considered: LED and incandescent fixtures. The number of light fixtures was varied, along with orientation of the fixtures with respect to wind flow and wind velocity. Time histories of wind force on the lighting assembly projection were used to determine dominant frequencies produced by the wind flow and were compared with the first three natural frequency modes of poles commonly used in Kansas. This approach can provide insights for wind behavior as it flows across the assemblies, and which, if any, structural modes it may excite. This approach isolates the lighting assembly; therefore, it does not provide insight as to how the lighting assembly and pole respond together.
